Additional tasks are required to <br /> address City-requested changes to the alignment and street widths, delays in the project, outdated environmental <br /> analysis, new case law regarding traffic analysis, and updated air quality modeling requiring supplemental <br /> technical analysis; all of which could not have been foreseen at the time of our original proposal. Our scope of <br /> work and cost estimate have been structured to follow our original task numbering and describe the changes or <br /> supplemental work that must be completed for each task. <br /> Project Background <br /> The kick off meeting for this project was on March 1, 2009. Since the kick-off meeting, alternative concepts have <br /> been prepared that evaluate combinations of 100-, 110-, 120-foot right-of-way within varying segments of <br /> Warner Avenue. The concepts address property take on the south only, the north only, and on both sides of the <br /> street. The City has requested additional engineering designs to identify alternative bike crossings that would <br /> connect the bike path on the north and south sides of Warner Avenue without the need for a midblock traffic <br /> light. Additionally, the City would like to see alternative plans that would minimize property take and reduce the <br /> number of remnant parcels along the north side of Warner Avenue. <br /> Revised Scope of Work <br /> <br /> ENVIRONMENTAL <br /> This request includes the following tasks beyond our approved scope of work: <br /> <br /> TASK 1. ENVIRONMENTAL STUDIES <br /> No change; this task is complete (Phase I hazards assessment). <br /> TASK 2. DATA COLLECTION <br /> No change. Data Collection is complete for the initial phase of the environmental document. <br /> <br /> TASK 3. INITIAL STUDY <br /> New alternative designs for the bike path crossing and to minimize property take will be developed. The Initial <br /> Study will be updated based on the final preferred alignment and preliminary engineering plans. <br /> <br /> Orange County ~."ri i y;ti'..
